1. Which tissue primarily provides ligamentous stability to a synovial joint?
A. Muscle
B. Tendon
C. Ligament
D. Articular cartilage
Answer: C
Ligaments connect bone to bone and provide primary passive joint stability.
2. A patient with excessive subtalar pronation may benefit from which
orthotic modification?
A. Soft heel cushion
B. Medial heel wedge
C. Lateral heel wedge
D. Rocker sole
Answer: B
Medial wedging reduces pronation by shifting the hindfoot laterally.
3. The primary goal of a KAFO with a locked knee joint is to:
A. Increase knee flexion during stance
B. Improve swing-phase control
C. Provide maximal coronal and sagittal plane stability
D. Promote knee hyperextension
Answer: C
A locked knee KAFO stabilizes the knee in all planes.
,4. Which nerve is most commonly compressed in carpal tunnel syndrome?
A. Ulnar
B. Radial
C. Axillary
D. Median
Answer: D
The median nerve passes through the carpal tunnel and is compressed in CTS.
5. The purpose of a SACH foot in a prosthesis is to:
A. Increase energy return
B. Allow rapid push-off
C. Provide shock absorption and stability
D. Allow triplanar ankle movement
Answer: C
SACH feet offer basic stability and cushioning but limited dynamic response.
6. Which amputation level preserves the adductor muscle insertions best?
A. Hip disarticulation
B. Transfemoral
C. Transtibial
D. Syme's
Answer: C
The transtibial level preserves knee structures and adductor origins at the
pelvis.
7. A scoliotic curve is considered structural when:
A. It disappears during forward flexion
B. It measures <10°
C. Caused only by posture
D. It remains during side bending
Answer: D
A structural curve is rigid and does not correct with movement.
, 8. Which suspension is commonly used in a transfemoral suction socket?
A. Pin lock
B. Lanyard
C. Total suction (skin fit)
D. Belt suspension
Answer: C
Suction suspension requires an intimate fit and airtight socket.
9. What is the primary purpose of a metatarsal pad?
A. Increase ankle dorsiflexion
B. Redistribute forefoot pressure proximally
C. Reduce heel strike force
D. Limit midfoot motion
Answer: B
It shifts pressure from metatarsal heads to shafts.
10. A thoracolumbosacral orthosis (TLSO) primarily limits:
A. Shoulder mobility
B. Trunk flexion, extension, and rotation
C. Hip abduction
D. Cervical extension
Answer: B
TLSOs restrict spinal movement to promote healing or correct deformity.
11. Most knee disarticulation prostheses require a:
A. Polycentric ankle
B. Bulbous socket design
C. High trim line
D. Hip joint support
Answer: B
The condyles require a bulbous socket for suspension.
